Title: Impact extrusion device
Inventor: BULLIARD JEAN-MAURICE
IPC: B21C23/18
Filed: 1980-03-05
Abstract: The impact extrusion device, intended for the manufacture of packaging tubes (4) which are capped by a diaphragm (21) bordered by a peripheral bead (20), includes a die (18) whose bottom is formed by a bolster (counter-punch) (19) mounted so as to slide in the die (18) and being pressed onto the impact bearing plate by means of an elastic element. The head of the bolster (counter-punch) (19) is provided with peripheral circular die sinking, the cross-sectional contour of which has the shape of a continuous line having inflections of the same direction and with no discontinuities. The flow of the metal during the extrusion is thus standardised, which enables sound diaphragms to be obtained beyond the normal limiting diameters. <IMAGE>

Title: Device for the application of a current flowing in one direction through the skin of a living body
Inventor: TAPPER ROBERT
IPC: A61N1/04
Filed: 1978-10-13
Abstract: Use of conventional electrodes and direct current often results in iontophoretic burns on the patient which generally occur at the negative electrode. In order to avoid such burns, at least that area in which the negative electrode (1) is in contact with the skin (2) is covered with an intermediate layer (4) of an electrically conducting, metal-free, porous, preferably moistened material which is more than three millimetres thick. On use of this structure of the negative electrode, the size of the positive electrode can be increased, so that the current used for the treatment can be increased while at the same time the adverse effects can be reduced. It is possible to use positive and negative electrodes arranged alternately and next to one another. <IMAGE>
